APPARATUS FOR WITHDRAWING FLUIDS FROM YESSELS.

Apparatus in accordance with my invention comprises two ejector sections arranged in one unit, the first section consistin'gyof a plurality of ejectors "operating in parallel, ending from one or more suction chambers,

and arranged aroundthe' axis of an ejector which forms the second section, the discharge from the ejectors of the first section pbeing around, or forming an annulus around, the nozzle of the ejector of the second secinto the second section.- These section and thence throng said passages,

tics, The axes of the ejectors in the first section preferably converge to a oint in ad vance of but onthe axis of the e ector forming the second section.

Between thedischarge bining tubes of the ejectors in the first section and the point of deliveryto the ejector formin the second section, I may provide a cham or or the like which is or maybe divided by longitudinal guide vanes or their eduivalent ,i-ntopassages through which the discharge from-the first section is delivered passages, when employed, are gradually deve by the longitudinal guide vanes, so as to terminate in an annulus thron h which the discharge of the first section is delivered to tlie-=-seco'nd section, the areas of successive cross sections in each of said passages being charge from the combinin tubes ofthe first maintained approximately constant.-

The nozz'jles ofthe ejectors may be sup plied with operating fluid of any kind, but

when supplied with steam, a steam su ply chamber may be formed at at distance rom Specification a: Letters Patent.

to the ejector in the second section, the apparatus being conveniently divided or constructed 1n parts with the object of facilitating manufacture. v

The operating fluid may be supplied to the ejectors at any suitable pressures, and it. is to be understood that in all cases the proportions of the ejectors and the fluid pressures employed depend on the particular requirements for whichthe a )paratus is used, for example, in the case 0 steam condensers the pressure or pressures of the operating fluid depend on the particular air and vacuum conditions associated with any particular plant.

The apparatus may be designed so that the ejector sections may be used separately or together. Furthermore, the design may be such that any one section has a greater discharging capacity than the other when used separately, so that by the use of either or both sections, varying discharging capacities can be obtained.

' In the specification of my Lette1's,1atc11t No. 1 2467711917 I have described air withdrawlng apparatus comprising an air withdrawing e ector, a controlling ejector, and

anyau' delivery ejector which operate in series under certain pressure differences. In the specificatlon of an application made by me on the 25th October 1917, .under Serial Number 198549, I have described the use of an airwithdraw-ing ejector and a controlling ejector in combination in' series with a water operated ejector or an air pump.

Apparatus constructed in accordance with a my present'invention maybe very advantageously employed for use as the 'air withdrawing and controlling ejeotors referred to in the above-mentioned specifications.

The accompanyingdrawings illustrate by -lli way ofexample convenient forms and up plicati'ons' of my invention.

Figures 1, 2, 3, 4, and 6 illustrate one convenient form of apparatus which is particularly suitable. for the withdrawal and discharge of aerated vapor from steam condensers. Figs. 7 8, 9 andshow the up paratus described with reference to .Figs. 1 to 6 in combination with other discharging apparatus, which in the examples shown are employed for the removal of aerated vapor from steam condensers.

With reference to Figs. 1 -to 6. Fig. 1 shows an elevation'of a unit comprising two ejector sections a and b, the. part of the drawing above the center line being an outside view, and the part below a sectional view. The first section (1 consists of a number of ejectors arranged in parallel, each ejector being formed by a nozzle w and a combining tube 5 The second section 6 consists of a nozzle 4) and a combining tube h.

If the conditions are such that the condensing receiver f is not required, it may be omitted.
